ber is adaptedzto project cross-wisethrough the openingsin,the'piercerand engage beneath the wall of the container flbOtltwthG opening caused by the nsertion of the piercer.

According to the present invention a rod is rotatably guided and adjustable vertically in the device, and passes to the exterior thereoi where it is operable. The cross piece is fixed upon the lower end of the rod and in its normal position lies within the piercer point while ithe openings in the piercer are so formed that when the rod is rotated in one direction such cross piece will be projected beyond the walls of the piercer and when the rod is rotated in the opposite direction the cross piece will be rotated back to its normal position clear of the Walls of such piercer. A butterfly nut is threaded upon the rod immediately above the top of the device to bear upon the neck of the spout whereby the rod may be drawn upwards.

The invention is illustrated in the accompanying drawings, wherein Figure 1, is an elevation of the device.

Figure 2, is a sectional plan on line A-'A, Figure 1.

Figure 3, is a cross sectional elevation taken along line 13-13, Figure 2.

Figure 4, is a sectional elevation of a modified form of the device in position upon a container.

Figure 5, is a cross section along line C-C, Figure 4.

Figure 6, is asection through the piercer.

Referring to the drawings, the device consists of a tapering piercer point 1 having a projecting spout 2 arranged approximately at right angles to the piercer point. The flange 3 is provided at a position between the spout and the piercer point and below this flange a rubber or the like washer 4 is placed. Immediately below the washer holes 5 and 6 are respectively formed in opposite walls of the piercer. These holes are staggered in relation to each other, as shown in Figure 6. Passing through the device is a rod 7 guided in a neck 8, the

hen rotated a half turn assumes the position lowerend oi? the rod ending in a cross member 10 adapted whenl n the posit on shown inFigure 2, toproject transversely through the holes 5 and tiin the walls of the-piercer. -th the metal of the conta ner, but when shown indott-ed lines in Figure 6, and is then clear, of the piercer. The upper endot the rod has a handle 11 while a butterfly nut 12 is threaded upon the rod above a washer 13,:and by screwingdown the nut the cross member 10 is drawn upwards so to force the metal of the container 14 tightly against the rubber washer tin; order to provioe a liquid tight joint between the container 14 and the shoulder 3. In cross sect on the piercer .15 made, rectangular so that the member 10 maybe seticlear of the walls of the piercer when rotated toithe po: sition shown in dotted lines, but when in the position shown in full lines, it projects beyond the walls as before described.

in the construction shown in Figures 1 to 3 it will be seen that liquid will pass from the pier-oer into a chamber 15. This chamber comn'iunicates by means of a port 16 with a passage 17 in the spout 2, such port 16 being located in a dividing wall 18. The port 16 is adapted to be closed by a plug 19 having a washer 20 secured by screw 21.

To insert the device the piercer point is simply pushed through the metal of the container, the rod 7 rotated so that the end of the cross member 10 will engage beneath the metal of the container and, by screwing up the nut 11, such cross memliier will force the metal of the container against the washer so as to provide a liquid tight joint. The flange 3 is slightly curved upon its underside, as shown in order to ensure a better joint when the device is screwed up. The end of the spout may have a small. piercer point for the purpose of piercing a vent hole in the container.

To empty the contents the container is turned so that the liquid will be able to flow from the spout 2 and the plug 19 is then rotated to permit liquid to flow from the chamber 15 through the port 16. To disconnect the device the nut 12 is slacked and the rod rotated so that the cross member will assume the position shown in dotted lines in Figure 6. The device may then be easily removed.

In the device shown in Figures 4 and 5, the spout 2 is open at the top while the chamber continues through the spout. Into the top end of the chamber 15 a tube'23 is inserted of sufficient length to project slightly above the top 01" the container. It Will be noticed that the spout 2 tapers and a plug 24 is attached upon the end of a wire loop 25 which passes up through the tube 23 and ends in a handle 26. The plug is secured by a pin 27 which passes through a loop 28 formed by the Wire of the loop 25. In the position shown in Figure 4, the plug has been drawn upwards permitting the flow of liquid from the container through the spout 2. Vhen sutiic'ient liquid has been drawn ofi the plug is simply pushed downwards so as to close the tapered opening in the spout.

hat I claim is 1. In a device having a piercer point combined. With a spout and flange, a rubber Washer located on the underside of the flange, a cross member adapted to normally lie Within the Walls of the piercer but upon rotation to project crosswise through openings in the piercer and engage beneath the metal of the container; said cross piece fified upon the end of a vertical rod guided and adjustable vertically in said device, said rod passing to the exterior of the device Where it is operable, said openings in the piercer point being so formed that when the rod is rotated in one direction said cross piece will be set clear of the Walls of the piercer and when rotated in the opposite direction said cross piece Will be projected beyond the Walls of the piercer, substantially as described.

2. In a device according to claim 1, a plug to stop flow from the piercer to the spout, whereby the flow of the liquid from the container through the spout is controlled, and means to operate said plug from the exterior of the device, substantially as described.

3. In a device according to claim 1, the upper end of said spout being open, a tube fitted into said open end, a Wire loop depending through said tube, a plug arranged on the end of said loop and arranged to close the tapered end of said spout, substantially as described.

In testimony whereof, I have signed my name to this specification.
